I apologize if this issue has been answered elsewhere. If it has, I would appreciate it if someone could direct me to those posts.

In stereo mode, when I connect a signal to just the channel 1 input and the corresponding channel 1 output is connected to an 8 ohm speaker – not only does the channel 1 signal meter on the front of the amp show activity – but the channel 2 signal meter (with gain level off) also illuminates – with no channel 2 input or output connections. The amount of signal activity on the channel 2 meter seems to match the channel 1 meter. This happens on both new amps.

Then, I made the same connections on channel 2.

I turned the gain down on channel 1 and just using the channel 2 input and output – only the channel 2 meter illuminates and shows activity – the channel 1 meter did not show any signal activity.

In stereo mode, with the channel 2 gain level off, why would the channel 2 signal meter show the same signal activity as channel 1, with no channel 2 input or output connections?

I have found the same behavior with my units: When signal is input to Ch1, Ch2 shows activity! Only the Signal led is lit though on Ch2.Do you have more than the Signal led lit?I have advised Crown and am waiting for a reply to this behavior.Stay tuned!
